Sample Development

• Sample making

  OEM manufacturers produce samples according to technical agreements: prioritize the use of mass-produced raw materials and production lines of the same type to ensure consistency between samples and bulk products; Synchronize output of 'Sample Report': including production parameters and testing data.

• Customer confirmation and iteration

  Customers can conduct testing on samples to verify whether their appearance, size, and performance meet the standards. They can commission a third-party testing agency to issue a report; Feedback modification suggestion: If the sample does not meet the standard (such as "surface scratches exceeding the standard" or "performance test not passing"), the OEM manufacturer needs to analyze the reasons. After adjustment, a second sample should be made until the customer signs the "Sample Confirmation Letter".
